Key ASIC SPG101 SoC Chip Evaluation Board



Powered by unique ASIC approach, KeyASIC’s leading edge 32bits CPU SOC reference platform is an ideal engineering tool to develop a “combo” SD card which can integrate one SDIO plus one SD memory functions into a regular SD form factor card solution.


Microprocessor and General Architecture

  • High performance 32bits CPU core with clock rate of 200MHz
  • Interrupt Controller
  • Internal AMBA (Advanced Microcontroller Bus Architecture) (AMBA2.0, AHB/APB)
  • DMA Controller to manage accesses to external memory
  • JTAG support for debug

Memory Subsystem

  • SDRAM Controller for 64MB external SDRAM, supporting 16-bit SDRAM interface for single-chip SDRAM implementation at 166MHz
  • Auto-load Flash Controller for external NOR Flash – can support up to 32MBytes of NOR Flash
  • SSI interface can program to NOR-Flash control for software to read/write NOR-Flash.

SD Interface
